• Summary of best evidence for targeted body temperature management in patients with severe neurological illness (2026) · doi

  This evidence summary incorporated systematic reviews, clini- cal guidelines, and expert consensus statements, each with unique strengths and limitations. Systematic reviews provide rigorous syn- theses of primary research but may be limited by study heterogene- ity and publication bias. Clinical guidelines offer structured recommendations but can suffer from slow updates and institu- tional influences. Expert consensus statements, while valuable for rapid guidance, are inherently subjective and lack robust empirical support. Additionally, while we employed a comprehensive search strategy following the “6S” model, it was limited to Chinese and English publications. This may have introduced language bias and led to the omission of relevant evidence published in other lan- guages. Furthermore, despite searching multiple databases, it is possible that some systematic reviews meeting our inclusion crite- ria were not indexed or were unpublished. To mitigate the impact of these limitations and any single evidence source being missed, we prioritized the integration and synthesis of recommendations from multiple high-quality, synthesized source types. The conclu- sions of this summary are therefore based on the concordance of evidence across these diverse sources, which strengthens their reliability.

• Sex-related differences in Huntington‘s disease: a scoping review (2026) · doi

  Our scoping review has some limitations. We only searched two electronic databases – PubMed and Google Scholar. Since Google Scholar returned over 9,000 results and the first 500 screened by relevance filter covered suf- ficient relevant studies, this should be adequate for the scope of this review. Nevertheless, we cannot rule out that some studies may have been missed by not includ- ing additional databases. Another limitation arises from methodological inconsistencies in the included studies, where confounders, such as medication, comorbidities or age have not been included in the study statistics and therefore could distort results especially in the phenom- enology of the disease.

• Could behaviour change interventions be incorporated into cardiac rehabilitation programmes for insomnia and poor sleep quality management? A scoping review (2026) · doi

  This scoping review can be used in conjunction with exist- ing literature regarding the use of different BC techniques for patients specifically with CVD. This review highlights the potential benefits and feasibility of utilising BC inter- ventions for patients living with CVD, with the intention of inspiring further consideration into how they may be imple- mented into an established care programme, such as CR. In terms of strengths, this review utilised a methodology guided by frameworks and established clear inclusion and exclusion criteria to inform result selection. Utilising mul- tiple medical databases provided access to a high number of articles, which is beneficial when attempting to meet the aim of collating valuable and insightful data. Yet, due to the complexity of this topic and independent researcher screen- ing the results, it is reasonable to assume some relevant arti- cles may have been missed. The selection of databases may have also contributed to the relatively small sample size for a scoping review, first due to the limited dataset available within PsycINFO and CINAHL+. Furthermore, conduct- ing a search across the Cochrane library produced a large amount of unpublished clinical trials, resulting in 32 articles and the results of those that may have been relevant being omitted from this scoping review. As a scoping review, quality appraisal assessment was not conducted. Although including extensive heterogeneous data has provided opportunity for a comprehensive under- standing of the topic, the lack of opportunity for general- isabilty cannot be disregarded. If repeated, future authors may consider the appropriate statistical analysis of the data collected to quantify the heterogeneity to produce increased robust conclusions. Furthermore, recommendations taken from evidence which have not been critical appraised should always be considered with caution and be combined with results interepreted from uniform, standardised trial.
